Abstract	Introduction. ? There are 29 species of Sphaeroma currently known (Har rison & Holdich, 1984). Most species inhabit shallow-waters and some penetrate into waters of low salinity, particularly those which are wood-borers (Holdich & Harrison, 1983). Sphaeroma serratum (Fabricius) has a wide geographical range, i.e. Atlantic coasts of Europe, N.W. Africa, the Canaries, Madeira, the Azores, the Mediterranean, Black Sea, Suez Canal, South Africa, Western Australia (Monod, 1931; Omer-Cooper & Rawson, 1934; Harvey, 1969; Kensley, 1978; Holdich & Harrison, 1983). Its occurrence in South Africa and Western Australia is probably a result of man's activities through shipping. {Sphaeroma walkeri Stebbing has the widest geographical range of any Sphaeroma species and has been dispersed synanthropically to many of the world's ports (see Carlton & Iverson, 1981)). Sphaeroma serratum oc curs in a wide variety of habitats but is most commonly found under intertidal and shallow-water stones, in empty mollusc shells and, on rocky intertidal coasts, in upper shore crevices (Lejuez, 1966; Naylor, 1972; Harvey et al., 1973). It is very tolerant of desiccating conditions (Charmantier, 1973; Harvey et al., 1973), and can also tolerate brackish water to some extent, but not as well as Sphaeroma hookeri Leach and S. rugicauda Leach (see Harvey et al., 1973). All the records known to the authors cite Sphaeroma serratum as occurring in fully marine or estuarine situations. Observations. ? In the Faiyum depression 100 km south west of Cairo in Egypt is a large, closed, inland body of saline water Lake Qarun (200 km2, 40
